CUFF-BUTTON.

' Application illecl March 24,1899. Serial No. 710,324. (No model.)

Be it known that I, HENRY A. L. LIBAIEE", of New York city, county andState of New York,have invented new and useful ImprovementsinCuff-Buttons, of which the following is a specification.

This invention relates to a separable cuffbutton which is madespringless and so formed that the elasticity of the cuff itself willprevent the two sections of the button from becoming accidentallyseperated.

In the accompanying drawings, Figure lis a perspective view of a cudprovided with my improved button; Fig. 2, atop view thereof; and Fig. 3a detail perspective View of the two parts of the button, showing themseparated.

The letters a a' represent the two heads of the button secured at auinclination to a stem b and a tube c, respectively. The stern b is of adiameter to iit into the tube and carries a laterally-projecting pin b.The tube c is provided with a bayonet-slot c', which merges into areturn-pocket c2. At the free end of the tube c there is formed a collaror flange d, which is cut away opposite the slot c', so that the latteris accessible to the pin b. The slot c' extends only along the innerpart of the tube c, and the pin b is placed at a distance from the endof the stem h. Thus when the two sections of the button are assembledthe tube will telescope the inner end of the stem only, while the outerend of the stern remains exposed, and consequently the collar d will beplaced at a distance from each of the heads a a.

In use the stem Z2 and tube c are slipped through the two buttonholes ofthe cuif A, and the stem is pushed into the tube and rotated, so thatthe pin b passes through the slot c' Ainto the pocket c2, when the partswill be properly connected. In this closed position one flap A of thecuff will be supported upon the stem b and bear normally against thehead a, while the other flap A2 will be supported upon the tube c andbear normally against the head ct'. Thus the natural elasticity of thecuff will tend to force the two parts of the cuff-button outward inopposite directions, so that the pin b is prevented from becomingunseated. Ii", however, either of the flaps A' A2 is subjected to outside pressure, as when the wearer bears upon the cu in writing, theflaps would be apt to be pushed off the inner ends of their respectiveseats b and c and upon the seat of the other flap; but as the button ismade springless this displacelnent of the cul would remove the outwardpressure against the heads et a and would render the parts b c liable tobecome separated. This tendency is, however, overcome Vby theseparating-flange d, which con nes each cuifsection to its seat andprevents it from passing over the edge thereof and upon the adjoiningseat. Moreover, if the sections do become separated the ange CZ willhold the section c a securely suspended from flap A2, while the pin b'Will hold the section b a securely suspended from ap A'.

To open the button, it is only necessary to force the heads inwardlyagainst the resiliency of the cuff and to then turn one of the parts, soas to disengage the pin b' from the slot c c2.

What I claim is- In a springless cuff-button, the combination of stem bhaving inclined head a, and pin b', set back from the end of the stem,with tube c, having inclined head cd, and a bayonet-slot c', c2, thatextends along the inner end of the tube only, and with a collar d,mounted on said inner end and cut away op posite to slot c',substantially as specified.
